We have been using this since September and so far it works pretty well. There have been some minor issues, but I am very pleased with ZoneCD. We switched to the premium service (www.publicip.com) for $85 per year and I like it much better than the free one. The price is very reasonable in my opinion. We did try out the free service (www.publicip.net) and it worked well, but the premium service is easier to use and offers web based configuration.
I've been messing around with ZoneCD and when I run a closed session, the users are booted every 10 minutes and they have to log back in. Would you have any solutions or has this happened to you?
